3G Networks - Analysis and Simulation
GL’s UMTS Test Suite
GL’s UMTS test suite supports testing UMTS over IP, Optical, and TDM networks. These are discussed in greater detail below.
The representation of UMTS network above indicates the support of most of the interfaces by GL’s test tools. In summary.
- GL’s TDM probes, Optical Probes and PacketScan™ - an All-IP monitoring and analysis probe, along with NetSurveyorWeb™ allow centralized monitoring of entire UMTS network
- GL’s VQuad™ is used for end-to-end Automated Voice, Data & Video Quality Testing with speech metrics such as PESQ, and POLQA, combined with other metrics such as delay, packet loss, drops, and more
- GL’s general-purpose protocol simulation tool - MAPS™ - supports simulation of signalling and traffic over UMTS interfaces.
- Wide range of codec support, including AMR WB, and extensive per-call reports
